Hmmm, further testing indicates that I fumbled the mix. Chemistrynever was my stong point! I remember the Chem labs in college...every week, somebody in my group would break all the glasware and we'd end up dry labbing it. Thank G-d for plain M&Ms!

Brad, are you mixing the Beutler recipe posted by Ole in the APUG Chemical recipes section?
(there was a url link here which no longer exists)
The Beutler A solution all by itself should blacken (or at least turn dark gray) a piece of exposed film.
Beutler A solution:
0. (forget the Calgon - it's just a water softener)
1. Measure out 10 grams of Metol
2. Measure out 50 grams Sodium Sulfite (anhydrous)
3. Put 750 ml of water at 40 deg. C in a mixing container.
4. Dissolve a pinch of the Sodium Sulfite first, then stir in the Metol
5. After all the Metol is dissolved, stir in the remaining Sodium Sulfite.
6. Add water to make a total solution volume of 1 liter.
You are finished mixing the A solution.
The Beutler C solution is pretty hard to mess up:
0. (forget the Calgon - it's just a water softener)
1. Put 750ml of water at 40 deg. C in a mixing container.
2. Measure out 100 grams Sodium Carbonate (anhydrous)
3. Stir the Sodium Carbonate into the water.
4. Add water to make a total solution volume of 1 liter.
You are finished mixing the C solution.
The Beutler D solution is easy:
1. Put 750ml of water at 40 deg. C in a mixing container.
2. Measure out 10 grams of Potassium Bromide
3. Stir the Potassium Bromide into the water.
4. Add water to make a total solution volume of 1 liter.
You are finished mixing the D solution.
